A sleeve f is attached to the side wall c of the container b through which the pipe d is inserted, and a flange joint g is attached to the inner end of the sleeve f to allow the pipe d to move in the axial direction. Support plate h that supports while regulating movement in the radial direction
It mainly consists of. In order to prevent radiation from leaking from the pipe penetrating portion of the container b, shielding members i and j are attached to the inside and outside of the sleeve 5 that projects inside the container. The inner shielding member i is adapted to fit inside the sleeve f, and is attached to the support plate h via a rod k and a collar l so as to be fixed at a predetermined position within the sleeve f. Further, the outer shielding member j is adapted to fit on the outside of the sleeve f, and is pressed against the side wall c of the container b via a stopper n of a band m attached to the sleeve f, as shown in FIG.

For this reason, if the outer shielding member j is installed at the factory, it will be difficult to attach and remove it on site, so the procedure of attaching the outer shielding member j to the sleeve f on site and then welding the flange part o of the flange joint g is performed. It was necessary to step on it, and once the flange part o was welded, it was difficult to remove the outer shielding member j. Furthermore, since the structure is such that the movement of the pipe d in the radial direction g is regulated by the shearing force generated in the bolt p of the flange joint g, the durability of the bolt p tends to deteriorate.

る。[Means for Solving the Problems] In order to achieve the above object, the present invention attaches a sleeve to the side wall of the reactor containment vessel so that the piping passes through it, fits a shielding member on the outer periphery of the sleeve, and In a through-piping support device in which a support plate is attached to an end of a sleeve to support the piping in order to restrict its movement in the radial direction, the outer diameter of the support plate is set on the outside of the sleeve so that the shielding member can be fitted into and removed from the outer diameter of the support plate. The diameter of the support plate is approximately equal to that of the sleeve, and an engaging portion that engages with the inner peripheral portion of the sleeve is formed on the support plate to restrict movement in the radial direction.

よりスリーブ５の端部に固定される。 In FIG. 1, 1 is a reactor containment vessel, and 2 is a building that houses this vessel 1. A sleeve 5 for inserting the piping is attached to the side wall 3 of the container 1 by welding. Piping insertion hole 6 that restricts the movement of
A support plate 7 having a diameter is attached. Particularly, the support plate 7 is formed so that the outer diameter D is equal to the outer diameter of the sleeve 5 so that the annular outer shielding member 8 that is inserted into the outer periphery of the sleeve 5 can be inserted into and removed from the axial end of the sleeve 5. An engaging portion 9 that engages with the inner peripheral portion of the sleeve 5 is formed in the sleeve 5 to restrict its movement in the radial direction. The support plate 7 is fixed to the end of the sleeve 5 by bolts 10 appropriately placed around the periphery, as shown in FIG.

５内の所定位置に位置決め固定される。 Further, an inner shielding member 11 made of a lead plate is fitted into the sleeve 5, and one end of this inner shielding member 11 is fixed to the other end of a rod 13 which is fixed to the support plate 7 by tightening a nut 12. It is positioned and fixed at a predetermined position within 5.

れる。 Further, due to the thermal expansion and contraction of the container 1, the piping 4, etc., a force is generated in the piping 4 to move it in the radial direction, but this force is transmitted from the engaging portion 9 of the support plate 7 to the sleeve 5. Since the shearing force applied to the bolt 10 is reduced, the durability of the bolt 10 can be improved.
なお、サポート板７の外径Ｄは、外側遮蔽部材
８が嵌抜できれば、スリーブ５の外径より若干大
小があつてもよい。 Note that the outer diameter D of the support plate 7 may be slightly larger or smaller than the outer diameter of the sleeve 5 as long as the outer shielding member 8 can be inserted and removed.
［考案の効果］
以上要するに本考案によれば次の如き優れた効
